1) Do not use as through valve. 2) The kvs value of the mixing passage (B-AB) is lower by approx. 30%. Therefore, the max. throughflow is practically the same as in

the load-related control passage.

Complete type code for valve and actuator with F variant Valve: For F variant, technical data and accessories, see table of valve types Actuator: For F variant, technical data, accessories and fitting position, see Section 51 Example: BUL 015 F310 / AXS 215S F122

pmax [bar]= max. permissible pressure difference across the valve at which the actuator can still firmly open and close the valve. Figures stated are for a static pressure of 6 bar; at a static pressure of 16 bar, the values are reduced by 15%.

ps [bar]= max. permissible pressure difference across the valve at which, in the event of a malfunction, the actuator can close the valve. Close/off pressure

The pressure difference across the valve in control mode that the force of the drive can overcome. In this mode, a reduced serviceable life can be expected. Cavitation, erosion and pressure surges may damage the valve. The values stated apply only when the valve is fitted to the actuator.

Operation The control passage (A-AB) is closed and the mixing passage (B-AB) is opened by pressing the spindle in; it is returned by spring pressure (the spring is in the valve). The AXT 211 thermal drive can be used to move the valve to the OPEN or CLOSED position. Used in combination with the ‘normally closed' drive version, the control passage closes in the event of power failure.

Used with the AXS 215S actuator, the valve can be moved to any position. Depending on the settings of the DIP switches, the valve is moved continuously with a control voltage of 0...10 V / 10…0 V or 2…10 V / 10…2 V. The control signal is then assigned linearly to the valve stroke and provides the equal-percentage characteristic in the valve. The positioner integrated within the actuator controls the actuator in relation to the settings of the DIP switches and the positioning signal y. The actuator posi-tions the valve and, as soon as the position has been reached, it stops. Used with the AXM 117 motorised drive, the valve can be moved to any position. On the AXM 117S (with positioner), the valve is moved continuously by a control voltage of 0...10V–. Variants: F202 opens (and F302 closes) the control passage as the control voltage rises. Used with a continuous drive (0...10 V), the practically equal-percentage characteristic provides optimum control.

The kVS values in the bypass are about 30% less than those of the control passage. Therefore, the flow resistance of the load is taken into account, so that the total throughflow in every stroke position remains fairly constant. The practically equal-percentage characteristic in the control passage provides optimum control when used together with a continuous 0...10 V drive.

Engineering and fitting notes The final control element can be fitted in any position except facing downwards. The ingress of condensate, dripping water etc. into the drive should be prevented. In order to prevent cavitation noise from affecting rooms where quietness is essential, the pressure difference across the valve should not exceed the following values:- BUL 010 F .30 = 0.5 bar, F .20 = 0.6 bar / F .10 and F .00 = 0.8 bar BUL 015 F .10 = 0.6 bar, F .00 = 0.8 bar BXL 020 F .00 = 0.5 bar In order to restrain contaminants in the water (e.g. welding beads, rust particles etc.) and prevent the spindle seal from being damaged, we recommend the employment of collective filters, e.g. for each floor or feed pipe. The composition of the water should be in accordance with VDI 2035. Medium with coolant such as glycol, min. 16% max. 40%. When insulating the unit valve, the insulation should not extend beyond the cap nut or the bayonet ring on the drive.
